Abstract
The invention relates to a simple, economical and safe method for constructing a dam in a deepwater river. The dam related to the invention is composed of two parts: a main dam and an auxiliary dam (namely, a stone-baffling dam and a water-baffling dam). 1) The construction method of the main dam ( the stone-baffling dam) comprises the steps of preparing building block type prefabricated single-layer main dam building blocks with draining holes layer by layer in the upstream of a dam to be constructed, wherein a top view of the main dam is arch-shaped and an arch-shaped back faces coming water. 2) The prefabricated single-layer main dam floats under the help of floaters and is dragged to a main dam supporting point layer by layer, wherein the main dam supporting point has a firm and smooth foundation and two firm and durable sides, and meanwhile, an auxiliary dam material is filled in an upstream face of the main dam. 3) The construction method of the auxiliary dam (the water-baffling dam) comprises the steps of stacking and compacting accumulated matters such as stone blocks on the upstream face of the prefabricated main dam, wherein the accumulated matters have high specific gravity, and the grain size of the accumulated matters becomes small and thin from big till water hardly penetrate. 4) A waterproof film through which water cannot penetrate is pasted to the outer surface of the upstream face through which water hardly penetrate, and meanwhile, a protection layer is added to the upstream face of the waterproof film; and thus the construction of the dam in the deepwater river is finished.
Description
Affiliated technical field
The present invention relates to a kind of simple and easy, economic, safe dam building method, a kind of method of in deep water rivers flowing water, building dam.
Background technology
At present, the known dam form of building does not also have this dam building method.
Summary of the invention
Do not blocking the possibility of building dam under the abominable water environment of flowing water for not enough and blank, reduction dam cost, the dam security performance that improves, the creation of mankind of filling up simple and easy, economic, the safe dam building method in this area, the present invention provides a kind of method of in deep water rivers flowing water, building dam.
The dam that the present invention relates to is made up of key dam and auxiliary dam (promptly keeping off masonry dam and checkdam) two parts; 1, the building method of key dam (promptly keeping off masonry dam) is: successively make building block type at the dam yet to be built upper reaches and have dewatering orifice, the long-pending piece of prefabricated individual layer key dam (the top view archwise of key dam, the back of a bow is to coming water); 2, through float make prefabricated individual layer key dam floating and successively drag make it to float on the basis firm smooth, the robust key dam strong point in both sides is in place, fills the auxiliary dam material at the key dam upstream face simultaneously.3, the building method of auxiliary dam (being checkdam) is: pile up the great granularity that is not dissolved in water of stone geometric ratio at the upstream face of prefabricated key dam and taper to try one's best impermeable deposit and compacting from large to small.4,, add topping at the waterproof film upstream face simultaneously at the impermeable waterproof film of impermeable upstream face external pasting of trying one's best; Like this, just success of a kind of dam of in deep water rivers flowing water, building.The pipeline that discharges water of dam can pass through from the preformed hole of key dam (promptly keeping off masonry dam), adjutage route auxiliary dam (being checkdam) location.
The dam that the present invention relates to; Key dam (promptly keeping off masonry dam) longitudinal section can be made step shape, fish migration for ease, and each step section can be made the tank type; Flowing water flows into subordinate's tank step by step when the dam overflow, and fish can leap to upper level step tank step by step and leap to the dam crest waters at last.
Claims (3)
1. method of in deep water rivers flowing water, building dam, its dam is made up of key dam and auxiliary dam (promptly keeping off masonry dam and checkdam) two parts; (1), the building method of key dam (promptly keeping off masonry dam) is: successively make building block type at the dam yet to be built upper reaches and have dewatering orifice, the long-pending piece of prefabricated individual layer key dam (the top view archwise of key dam, the back of a bow is to coming water); (2), through float make prefabricated individual layer key dam floating and successively drag make it to float on the basis firm smooth, the robust key dam strong point in both sides is in place, fills the auxiliary dam material at the key dam upstream face simultaneously; (3), the building method of auxiliary dam (being checkdam) is: pile up the great granularity that is not dissolved in water of stone geometric ratio at the upstream face of prefabricated key dam and taper to try one's best impermeable deposit and compacting from large to small; (4), at the impermeable waterproof film of impermeable upstream face external pasting of trying one's best, simultaneously add topping at the waterproof film upstream face.
